This invention relates to an improved log confining, floating, and anchoring boom for use in rivers and analogous bodies of water to facilitate handling and transportation of a multiplicity of logs via the water route from a remote source of supply to a predetermined terminal.

It is a matter of common knowledge among those familiar with the logging industry In that buoyant enclosures are employed in river use for confining and floating a group of logs from the woods to a sawmill or other conditioning point. As a general rule the booms utilized for this purpose are themselves made up of a multiplicity of buoyant logs assembled in such a manner as to provide a raft or the like.

Being familiar with prior art devices, as

well as those devices now utilized in thesomewhat in the nature of an openwork pen, i

said structure being characterized by simplicityand durability and such in design and configuration as to better fulfill the requirements of a conveyance of this classification. In the drawings:

Figure 1 is a front elevation of a device constructed in accordance with the present invention.

Figure 2 is a top plan view thereof.

Figure 3 is the rear elevation.

Figure 4 is a section on the line 4.4 of Figure 3.

Figure 5 is a detail section on the line 55 of Figure 2.

Figure 6 is a detail section on the line 6-6 of Figure 1. As before implied, the structure, as a whole, has the general appearance and resemblance of a floating pen adapted to embrace and confine a plurality of logs so as to successfully float the logs from a predetermined point of loading to a satisfactory point of destination.

' As seen in Figure 2, the structure may be said to embody a front wall 7. a spaced parallel rear wall 8 and a pair of duplicate end confining walls 9 and 10 respectively.

The front wall as seen in Figure-1 is made wall is of a height less than the front wall;

that is, it is made up of a lesser number of logs 12. The end walls are made up of short transverse logs 13 and 14 all of the logs of the four walls being chained together. It is evident from Figures 4 and 5 that the logs are bored to provide holes and connecting chains 15 are passed'through these holes, the ends of the chains being provided with retaining elements orheads 16. This provides the desired connection between parts and also 65 provides for desired flexibility.

These chain connections between the parts also provide pivotal joints allowing the walls to be folded against each other to make the structure compact and convenient for transit portation purposes. Incidently, the logs of the front wall may be disposed in staggered relation to those of the rear wall so as to permitthem to nest one within the other to provide for this compact collapsing and folding. I

Attached to the front wall, and also to the back wall if necessary, is a perpendicular post 17 detachably and adjustably mounted in place by a retaining chain 18. This post 17- -So bridges the spaces between the longitudinal and horizontal logs 11 so as to form a guard to prevent escape of the out timber (not shown) from the space within the confining walls of the so-called floating pen.

The numerals 19 designate anchoring and draft chains sometimes used when the water is exceedingly rough for temporarily anchoring the pen along the shore. It is obvious that the logs of the front wall are disposed in vertically superposed horizontally disposed relationship and held in such relationship by the connecting end members 13 and 14, said members 13 and 14 also constituting a means for connecting the rear wall witli the front wall and thereby making up a substantially rectangular enclosure for confining and floating the timber.

One other particular use to which this boom may be put is for preventing the logs from V I 3.0 If there should be a pier orlpiers erected 15 stream.
